Application med March 2,

ToVaZZ whom" z't may concewif and BORIs H. TEITELBAU-M, citizens of the United States, andresidentsof the city of New York, borough of Manhattan, in the county and State yof New York, have invented anew and Improved Dry-Cell Battery, ofwhich the following is a full, clear, and exact description.

This invention relates to dry cell batteries in which the active agents are kept separated or spaced preliminary to the time the battery is to bev put into use so as to prevent any possibledeterioration of the elements.

ln this present impro-vementone ofv our objects is to provide two distinct parts for each battery which are preferably kept en-A tirely separatedpreliminary to the operation Vof the battery, the parts however being adapted to be easily assembled when and only when the battery is to be put into use..

ith the foregoing and other objects in view the invention consists in the arrangement and combination of parts hereinafter a described and claimed, and while the in-V vention is not restricted to the exact de-y tails of construction disclosed or suggested herein, still for the purpose of illustrating 'a practical embodiment thereof reference is hadto the accompanying drawings, in which like reference characters designate the same parts in the several yiews, and in which- Figure 1 is a vertical sectional view of the cup orshell portion of one form of our present improvement.

) Fig. 2 is a vertical sectional view of a separate receptacle in which the depolar` izmg member is vplaced o'rcarried, the container being adapted to be discarded when the battery is .put into use.

Fig. 3 is a view-showing the resulting assembly of the parts shown in Figs. 1

andv 2.

Fig. Ltis -a'vertical sectional view'of a unitary battery complete but for the in" 'troduction of `a. suitable liquid or other zinc, or its equivalent, having a closed bottom and of any suitable length. This cup is ordinarily of cylindrical form but as to the form.- in cross section we do not desireto be unnecessarily limited. VVith-lA DRY-CELL BATTERY.

inthe bottom of the cu isa supply" of electrolyte 1 1 normally eld in place by means of a sealing member 12 of paraiiin,

or the like of a' nature adapted to be easily' ruptured or broken by force. -The zinc cup 10' forl practical purposes 1s preferably surrounded by means of a tube 13 of some suitable paper Vor other non-metallic material.

-`Within the upper` or' open end, of the cup 10 is removably fitted a. closure member or stopper 14 which may be of rubber, cork, or any other' suitable analogous material. vThis isprovided with a central hole 15 sealed 'while in idle condition by means of a paper' or other seal 16.

As indicated in Fig. 2 the depolarizing 18, or its equivalent, is normally shipped or handled in a cheap paprer or other cheap discardable container 19, having a cap of the same material. Withthe depolarzing member and conductor'housed as indicated the parts may be handled without any possible danger of deterioration'of the' active elements. They may be handled or wrapped separate, orthey may be wrapped together inthe condition indicated without danger.

W hen the battery is to be used the container .19 is opened and' destroyed ordiscarded and `the depolarizing member 17 is projected into the cup 10 after the stopper 14 is removedtherefrom, and after member 17 in which'is'fitted a4 carbon stick f the depolarizing member is forced into the `seal the open end of thecup making the battery complete Iand active. n

ln Fig. 1. the depolarizing member 17 is fitted more or less permanently in the stopper 14: and these parts are fitted into the cup 10, but without an electrolyte. The .battery as shown'in Fig. 4 may be regarded as complete as a commercial unit, but when it is to be used the stopper is removed from the upper end of the -cup so as to introduce any suitable iuidto act as .an electrolyte, such Huid being furnishedby the the dealer in any suitable separate container. A @We claimt 1. A dry .cell battery comprising two initially separateparts, one part consisting of a .metallic cup carrying within it an electrolyte, said cu having therein a sealed compartment for ousing the electrolyte, said compartment being formed partially of Walls of the cup and partially of an impermanently positioned Wall in the cup, and theother part including a depolarizing member having a carbon stick projecting therefrom, the complete battery being formed by plunging the depolarizing member into the cup containing the electrolyte after destruction or removal of said impermanently positioned Wall.

2. A dry cell battery comprising two initially separate parts, one part consisting of a metallic cup carrying Within it an electrolyte, said cup having therein a sealed compartment for housing the electrolyte, Said compartment being formed partially of Walls of the cup and partially of an impermanently positioned Wall in the cup, and the other part including a depolarizing member having a. carbon stick projecting therefrom, `and a stopper through which said carbon stick is adapted to extend, the complete battery being formed by plunging the depolarizing member into the cup containing the electrolyte after destruction or4 removal of said impermanently positioned Wall.
